Equivalent-forms reliability refers to the extent to which an individual obtains similar scores on equivalent, or parallel, forms of the same test.
Equivalent-forms reliability is a type of reliability measurement used in psychology to assess the consistency of test results when different versions or forms of the same test are used. It is also known as alternate-forms reliability. The goal of equivalent-forms reliability is to determine whether different versions of the same test are measuring the same construct or skill.
Here are some examples of how equivalent-forms reliability might be used:
-
Standardized tests: In education, equivalent-forms reliability is often used to ensure that different versions of standardized tests are measuring the same knowledge and skills. For example, if a student takes two different versions of a math test, the scores should be consistent if the tests are equivalent.
-
Personality assessments: In personality assessment, equivalent-forms reliability might be used to ensure that different versions of a personality test are measuring the same traits. For example, if a person takes two different versions of a personality test, the scores should be consistent if the tests are equivalent.
-
Clinical assessments: In clinical psychology, equivalent-forms reliability might be used to assess the consistency of results when different clinicians administer the same assessment or diagnostic tool. This can help ensure that the assessment is reliable across different settings and with different assessors.
To assess equivalent-forms reliability, researchers typically administer two versions of the same test to the same group of people and compare the results. If the scores are consistent between the two versions, it suggests that the test is reliable and consistent. Equivalent-forms reliability can be assessed using statistical techniques such as the Pearson correlation coefficient or the intraclass correlation coefficient.
